Abstract
The present invention describes separating components in a sample in an ion mobility based spectrometer using at least one matching property of the components other than the molecular properties in conventional ion mobility measurements in noble drift gases to enhance separation and resolution of the sample. Separation based on the matching property is realized by altering the drift media of the IMS. Besides altering drift media, energy level of ions and/or drift media are also controlled during the separation process. This invention describes an ion mobility apparatus wherein an energy source is added to the IMS that provides additional energy to the ions and/or drift media and tuning methods that involve selecting drift media and optimizing the energy level in order to achieve optimal performance.
